What is a potential reason for the revocation or suspension of a hoisting license?

Operating hoisting machinery under the influence of alcohol or drugs is a serious violation that directly impacts the safety of not only the operator but also those working nearby and the public. This kind of behavior compromises the operator's ability to control the machinery safely and makes it a significant risk factor for accidents and injuries on the job site. Regulatory agencies prioritize safety and have strict policies regarding substance use for operators of heavy machinery. Therefore, being found operating machinery while impaired can lead to the immediate revocation or suspension of a hoisting license as a measure to ensure the safety of all workers and the public.

In contrast, involvement in community service, having a clean driving record, and completing safety training do not present risks that would warrant revocation or suspension of a hoisting license. These actions are generally seen as responsible behaviors that contribute positively to a person's professional and personal conduct.
